China has been one of the most important markets for Dirac ever since we launched the first Dirac-enabled Chinese smartphone in cooperation with OPPO in 2012. Today, Dirac is the market leader in smartphone audio in China – providing audio optimization solutions for more than 10 manufacturers. While our breakthrough algorithms are well known in China’s mobile sector, we see great growth potential in the country’s other vertical markets including automotive, VR/AR and professional home audio.

In fact, earlier this year Dirac broke into the China’s automotive through a deal with BYD Automotive, the world’s leading electric vehicle manufacturer. In short time, another Chinese manufacturer will release a gaming headphone that is powered by Dirac VR/AR solutions.

With this influx in adoption of our premium audio solutions across the Chinese tech landscape, it was time to showcase Dirac’s full-line of audio innovations to a wider Chinese audience – and what better way to do so than at the 2018 Beijing International Music and HiFi show.

Room Correction: A New Concept for the Chinese Market?

At the show, we demonstrated our pioneering Dirac Live room correction solution on a NAD processor, and allowed visitors to listen to music and watch videos with Dirac Live ON or OFF.

It was interesting to learn that digital room correction – though prominent in the West – appears to be a relatively unknown and not widely used in China. Many visitors, whether audiophiles or professional music producers, arrived at our demo room without any prior understanding of digital room correction, though eager to implement anything to improve the sound of their home audio system.

After listening to the demo and asking lots of follow-up questions, they quickly accepted the concept of digital room correction and immediately began inquiring as to how best to integrate the technology into their audio system or become a solution distributor. 

Immersive Audio: The Future of Sound

Dirac believes that high-quality immersive audio represents the future of sound, whether produced over headphones, small portable devices, or VR headsets. At the show, we demonstrated our immersive audio solutions across a variety of consumer devices.

Visitors interested in portable speaker immersive audio got a chance to experience Dirac Panorama Sound, our speaker soundstage widening solution, on a Bose Soundlink Mini 2 speaker. Headphone enthusiasts had the opportunity to listen to four pairs of headphones equipped with both Dirac HD Sound, our headphone sound quality optimization solution, and Dirac Sensaround, our headphone soundstage widening solution. Those passionate about VR/AR experienced our breakthrough Dirac VR 3D audio solution on a virtual reality headset and a pair of headphones.

We were thrilled to hear from many visitors that our demos didn’t just showcase a marginal improvement in audio quality but rather a completely novel listening experience; they compared the performance of our Dirac-optimized devices to that of surround sound speaker systems and 3D audio spheres with sound coming from all directions.

While the concept of immersive audio is not new, its combination with high-quality sound and integration into portable consumer devices across a variety of product categories is truly pioneering.

Finding A New Perspective

As a research-driven company that primarily works with manufacturers and partners, we don’t often have the opportunity to interface directly with the end-user consumers. However, while at the show we took special notice of something powerful that occurred during these consumer demos: once attendees experienced our solutions, they seemed to feel as if they were part of something exciting – on the bleeding-edge of new innovation that not only transforms audio but rather entertainment in general.  

This feeling is something that we at Dirac experience every day and we were honored to share it with hundreds of attendees throughout the show. The show was a great success, as proven by one of the most common questions we received from attendees: “where can I get your solution?” We are thrilled to see Chinese consumers showing a genuine interest in Dirac and are excited to bring our world-leading algorithms to more products and categories in the country.

An Interview With Acclaimed Music Producer/ Songwriter Rami Yacoub

As part of a new Dirac Blog Series, we’re interviewing members of the audio and technology community about their lives, inspirations, and their passion for all things audio-related.

In our first installment of this series, we’re speaking with acclaimed music producer and songwriter Rami Yacoub. Rami began his professional career working with his Cheiron Studio’s production partner Max Martin on acts such as Britney Spears, NSYNC, Backstreet Boys, and more. He has since collaborated with many other artist, including One Direction, Nicki Minaj, Tiesto, AVICII, and Madonna, amongst many others.

In 2008, Rami launched his own Los Angeles and Stockholm-based production group, Kinglet Studios. In 2017, Rami joined forces with Dirac Research as an investor, music industry consultant, and a proud advocate for the advancement of audio optimization both in the music production industry and beyond.

Beijing Auto Show 2018: Steering to a New Era, Indeed!

Perhaps no industry is undergoing as dramatic a disruption as the automotive industry, as many manufacturers are transitioning from traditional automobile companies to, shall we say, mobile-entertainment-on-wheels companies.

That was clearly apparent at the recently-concluded Beijing Auto Show as automakers from around world gathered amid the swirling and industry-altering winds of change this market is experiencing. The show’s 2018 theme Steering to a New Era was most certainly apropos as information and communication technology are presenting unprecedented opportunities in today’s automotive space.

Mobile World Congress 2018: Audio is Almost Getting the Attention it Deserves

The 2018 Mobile World Congress has come and gone. Dirac was in attendance once again this year, and we left the event filled with a very promising feeling. And not at all thanks to the weather—which turned out to be the worst ever since we started attending the event back in 2006—but thanks to all the great people we had the pleasure of meeting, along with the equally great meetings we held with partners, journalists, and potential customers. 

Q&A on the New Dirac Live

As some of you may have noticed, things are happening with Dirac Live. We announced a brand new mobile version (for Android and iOS) at Cedia back in September, and in December we announced a new version of the PC based calibration tools (for Windows and OS X). So far so good. But we haven’t really said much about the hows and the whys, and what it all means for existing customers. Thus, the following was written with the intent of clearing up as many questions as possible.

The New Smartphone Trends that are Putting Audio Quality at Risk

So, you’re going to buy a new smartphone. What will you go for? A year ago, the must-have features on your list might have included: thin, lightweight, good camera, powerful chip, decent ROM&RAM, and great sound. Today, you would probably add to that a dual rear camera and large screen-to-body ratio. Yes, dual rear camera and large screen-to body ratio are some of the hot trends—among others such as face recognition, augmented reality and finger sensor—which, according to experts, will sweep over the smartphone industry in 2018. 


How to Obtain a Good Stereo Sound Stage in Cars

Designing a sound system for a car has a different success formula than designing a sound system for a living room. In a car, neither the loudspeakers or the people listening to them can be placed precisely according to the standard. Consequently, when listening to a recording, the stereo information is likely to be lost or, at least, severely distorted.

Here we will discuss the motivation and basic principles behind a Dirac technology called Dirac Virtual Center, which was developed to solve one of the classic problems in automotive sound system tuning: the near-side bias problem. 

Dirac Modes: Soundstage Control at Your Fingertips

Let’s say you have quite a firm opinion about how you want your music to sound. You want it to sound clean and tonally well balanced with just enough bass—not too much. You want the center image to be right there, dead in the center no matter how you move or where you sit, and you want the sound stage to stay symmetrically within 30 degrees to each side of the center image. 

Creating the Perfect Sound System with 3D Sound Reproduction

Over the last decades there’s been a lot of research devoted to figuring out how to record a sound event and exactly reproduce the original sound field in a different location. So far, this has not been possible to achieve for sound reproduction in a consumer environment with a reasonable number of loudspeakers. However, recently we have seen a lot of innovation in spatial sound reproduction, with applications ranging from TV and cinema, to games and VR.

How VR/AR Can Give Teleconferencing a Much Needed Makeover

In today’s global business environment, the ability to work remotely offers a huge work life improvement and ultimately saves on travel and environmental costs. One thing still holding us back, however, is the lack of proper teleconferencing systems. Despite the various solutions available, attempting to work remotely and conduct conference calls with 5-10 people located in various places across the globe is a hugely disappointing and unproductive experience.

Rescuing Smartphone Audio with Digital Soundstage Widening

It wasn’t too long ago that portable audio meant blurry playback on a Walkman, and portable movies were, of course, completely unthinkable. Yet today we consume portable audio in all kinds of environments and for a range of different purposes— for music, games, audiobooks, GPS systems, audio assistants like Siri… the list goes on. And it's all delivered in the convenient package of a smartphone. For the longest time portable audio also necessitated the use of headphones, and this is still very much the case. The tiny speakers in smartphones, while significantly better than ten years ago, can only do so much. Sure, advanced signal processing has enabled improvements in output level and sound quality over the past few years, but watching a movie on a smartphone without headphones remains a less than massive audio experience. What’s the problem?

3 Audio Trends Spotted at the 2017 Mobile World Congress

The Mobile World Congress (MWC) takes place in Barcelona every year. With over 100,000 exhibitors and visitors, it's by far the most important event in the industry. It also offers a key to understanding the trends of the future—not only in the mobile industry but in relation to how we live our lives. Mobile goes beyond mobile phones and everything you can think of is getting connected. Including some things you might not even imagine. 

Essential Audio Knowledge: Spectral Masking

Background noise is an unavoidable nuisance. Whether it's produced by roaring excavators or hurried crowds at a train station, and whether it’s obscuring a voice message from your boss or a listening session with a Tchaikovsky waltz, it's always annoying. Given urbanization trends, our environments will likely only get noisier—with more people living closer together, and the proliferation of mobile sound systems providing a whole new palette of noises and disturbances which were not present in the listening scenarios of yesteryear.

The Story of Dirac FilterLab: Great Technology Deserves a Great Tuning Tool

Our flagship automotive technology Dirac Unison uses our most advanced signal processing methods, enabling speakers within a system to work together to optimally reproduce each input channel–something which was previously impossible in digital room correction. While it’s a product we’ve always been proud of, up until January this year, the prototype tuning tool that came with it was not. It definitely worked, and offered all the required settings. But it was hard to maintain, and far from user-friendly.

CES 2017 Highlights, as Experienced from the Dirac Suite

It’s hard not to write something after returning from an event like CES, which leaves you with so many inputs and impressions, it nearly blows your mind. The entire place is so packed with innovations and ideas, it's like the entire world’s waited all year just to reveal what they've been busy hatching up in the seclusion of their basement. 

In HiFi, Virtual Reality Might Be Better Than Reality

As I write this, I'm listening to a recording of Joss Stone. Her voice sounds completely natural, hovering in the air just a few meters in front of me, placed distinctly at the center of my sound system, remaining there regardless of how I move my head. I can almost touch the ambience of the recording. The low frequency extension is great, the room modes are extremely well controlled. The listening room is remarkably well treated, with just the right amount of air and sense of space, and without the annoyance of comb filters or spectral coloration. It’s treated so well, I don’t need digital room correction. This is an experience you can’t get without a HiFi and room treatment budget of at least $100,000 USD. The funny fact is this: I’m getting this experience with a pair of headphones. And the sound system I’m referring to? It’s a virtual one. 

How to Make Headphones Stereo-Compatible

Have you ever wondered why music sounds so different on headphones compared to loudspeakers? It’s because, by design, headphones are not technically compatible with the stereophonic system. That isn’t to say you can’t still get great sound from headphones. Otherwise we wouldn’t be seeing the boom in headphone sales that we've been seeing the past few years (although it’s worth pointing out that some retail stores keep mirrors next to the headphone displays for customers who care more about looks than sound). In this post, I’ll be examining why music sounds different on headphones, and look into a technology that can upgrade headphone sound quality by several notches.

Big Sound in Small Packages: Is it Any Match to Hi-Fi?

Ever since humankind started creating music, the means, or equipment, for doing so have often been prohibitively bulky. True, there exists many small musical instruments, but the ones that can produce sound of sufficient strength and volume are typically really, really large; and an ensemble playing multiple instruments at once requires a lot of space indeed.

The Home Audio Industry Takes a Big Leap Forward: Multi-room, Garden Sounds, and Pitch-Perfect Raindrops

This year I returned to home audio after over a decade working in other industries and I was shocked to find that very little had changed since I’d been away. Generally speaking, progress has been relatively slow. In the 90s there was almost no home install and people tried their best to create a good listening environment, sometimes with a good result, sometimes not. But last month I discovered a very different picture of progress. I attended the CEDIA expo for home technology in Dallas and it was undeniable that technology is finally catching up with the imaginations of the people. Here are a few examples...
